Thank you, Shawn.

 

Reworked the spinner and cowling.  The earlier one I just made.  This go-around I drafted everything so spacings would be equal.

Remade the prop base.  Still has some tac on it.

Props in place.

Shady side.  Made sure the side walls were equally spaced this time.  4mm.

Where to begin?  The cowling nose is not razer sharp.  It has a rounded return.  While attempting to sand the nose to have a flat surface that I could round I sanded it crooked.  Lucky me.  So I had to start over again by putting it into the box and gluing pieces to the cowling to raise the edge to 46mm.  I only glued enough spacers to be able to glue a .040 thick by 30mm diameter disc onto it.  Then I filled the space with scrap and Apoxy  Sculpt and sanded it.  The cowling in now 47mm deep instead of 46.  I'm going with it.  I'm ready to move on.  I've spent weeks doing this.  I'll get back to it some other time.  I then cut out a 28mm disc and threaded it onto the prop shaft.  I drew a 28mm circle onto the glued on .040 disc which gave me a 1mm lip that, after I had cut out the interior, I could sand in the round.

Looks similar to before, but different.

Not a perfect match to the drawing but it will have to do for now.

 

Sincerely,

Thank you, Andy.

 

'We’re getting close on this one.'

Further than one may think.  Thank you Troy.  Apparently the P.E. directions were not in the bag.  They are inbound to you.

 

Thank you, Ray, Mike.

 

I figured out what was bothering me about the cowl.

DSCN6503_zps0zleaxkf.jpg

Here you'll see the 46mm dimension is from the cowling nose to a panel line set behind the wing leading edge.  Also note the cowling leading edge is 34mm, not 30.  The original 30mm was from a front view drawing where I had scaled the spinner diameter to match the above rather than the cowling leading edge to match the above.  Bummer.

 

DSCN6502_zpsiwfyvc0o.jpg

I have been measuring from the cowl leading edge to the wing leading edge when I should be measuring forward from the panel line shown on the right.  That's the making of the ventral vent.  Hmm.  Ventral Vent.  I like that.  Anyway.

 

DSCN6504_zpsy2z9izds.jpg

The right side of the tape, plus or minus 1mm, to the left is the new cowling leading edge.

Which is along the forward panel line.  Moving the cowling leading edge back solves two problems.  The major one, shape.  The minor one, how to make the gun trough.  But now the cowling must be seamlessly attached to the fuselage.  Always something new.

 

Thanks for looking in.  Until next time.

Sincerely,

Mark

Thank you, Brothers.

 

Am heading to Chicago this weekend for my eldest daughters graduation from a Masters program and to sponsor festivities.  There goes my modeling budget.  Not that I had much of one prior to now while paying for graduate school.  But she did make Deans List each semester so there is some solace.  Anyway, enough of my so-called financial woes.

 

I thought I would do a quick update as to where I am.

 

DSCN6506_zpsfkflwi76.jpg

Made this.

 

DSCN6507_zpspn1utf8b.jpg

Did this.  OUCH!

 

DSCN6512_zpsm5qdiii0.jpg

Made a styrene spacer.  It's the little white circle.

 

DSCN6510_zps7efpqzbs.jpg

Made a disc as a return, inserted it into the opening onto the spacer, making sure it was square to the outer face of the cut, and super glued it in place.  .040, I think.

 

DSCN6508_zps6h0gncrd.jpg

Glued a .010 disc to to that to achieve a new face.  Added Apoxy Sculpt where required and sanded to shape.

 

DSCN6517_zpshyve9ooj.jpg

Slipped on a new disc . . .

 

DSCN6518_zpspdtx7goe.jpg

. . . and drew a circle, giving me my inner diameter.  Now all I need do is cut and sand, as I did to the earlier rendition.

 

DSCN6514_zpsjksbv7xh.jpg

The guide.

 

DSCN6515_zps390bdfvx.jpg

Close enough for government work.  The yellow tape is the location of the panel line behind the gun trough.  17mm deep.  I'll cheat on the forward panel line, moving it back an extra MM.

 

DSCN6513_zps2ezqkp3r.jpg

More fun and games ahead.  The block of resin is a glued together solid casting of the vac pontoon.  Doesn't quite measure up to scale.  I'll see if I can use it as filler.

 

Thank you all.

Sincerely,

Mark

Three's a Charm.  Only took three times working on this to sort it out.

 

DSCN6528_zpsg5zjts3f.jpg

Cut it down to size once more and built in a return.

 

DSCN6524_zpsqpoyqjq3.jpg

This is what it is supposed to look like.

 

DSCN6529_zpsfuk7haln.jpg

And this is what it does look like.  Which, I am happy to say is the final.

 

DSCN6527_zpsywdk5r7w.jpg

Another view.

 

DSCN6526_zpsbvwuxi9l.jpg

And another.

 

DSCN6523_zpswjwfulzi.jpg

Last but not least.

 

I've also been working on the main float.  Trying to figure out the bulkheads.

DSCN6522_zpsh42tnjtj.jpg

Main float head on.  Rounded, not ovaled.

 

DSCN6519_zpszrklnobx.jpg

Made measurements on a scaled drawing.  Let's work with #3.  The panel line is 98mm from the nose and it's width is 44mm.

 

DSCN6520_zpsx4ygixux.jpg

#3 again.  The total depth is 32 mm.  I rounded it up.  The semi-round top depth is 24mm.  Which makes the ski 8,, deep.

 

DSCN6521_zpsvpj7yq3h.jpg

Drawings of locations 1, 2 and 3.  32mm diameter circle as depth. 24mm depth of float from top to edge.  44mm wide.  8mm ski.  All arcs are 1/8 of a diameter.

 

Thank you for looking.

Sincerely,

Mark
